the heat to generate steam in a waste heat boiler, which then drives a steam turbine. Steam turbines are one of the oldest and most versatile prime mover technologies. Heat recovery boiler/steam turbine systems operate thermodynamically as a Rankine Cycle, as shown in Figure 2. In the steam Rankine cycle, the working fluid—
In a steam boiler the heat from the flue gas is transferred to the water, which then turns into steam. Downstream of the boiler the flue gases are still high in temperature and are typically 50ºC or more above the steam temperature. Flue gas heat exchangers downstream the boiler can recover this waste heat and improve the boiler fuel efficiency.

HKB boiler solutions also supplies tailor-made waste gas boilers. In the fire-tube exhaust gas boiler, steam or hot water is produced by using heat recovery from flue gases and/or process gases produced by gas engines, diesel engines, gas turbines, or other combustion processes, such as incinerators.

Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as 'high grade heat', contrasting to 'low-grade heat' available from the generator cooling circuits. This high temperature and flow makes it well suited for utilisation in a …
The raw syngas from the gasification island is cooled in waste-heat boilers, recovering heat while generating steam at medium- and low-pressure level before being sent to the AGR unit for H 2 S removal. Depending on the AGR system employed, a COS hydrolysis step may be required.
